Alstroemeria plant named ‘Zantrice’

ABSTRACT

A new and distinct Alstroemeria plant variety producing flowers of attractive coloration.

Classification: The present invention relates to a new Alstroemeria sp. plant, in the family Amaryllidaceae.

Variety denomination: The new Alstroemeria sp. plant has the varietal denomination ‘Zantrice.’

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of Alstroemeria, which is a hybrid resulting from a cross of two unnamed, undistributed seedlings; namely, 290-032 as seed parent and 472-011A as pollen parent. The ‘Zantrice’ hybrid was produced as a seedling in a research station in Hillegom, the Netherlands, and combines the flower color of the seed parent with the stem quality of the pollen parent.

Asexual reproduction by dividing rhizomes, and by tissue culture, through successive generations in Rijsenhout, the Netherlands, has demonstrated that the combination of characteristics as herein disclosed for ‘Zantrice’ are firmly fixed and retained through successive generations.

SUMMARY OF THE INVENTION

The new variety of Alstroemeria, ‘Zantrice’, produces attractive flowers.

DESCRIPTION OF ILLUSTRATION

The new variety of Alstroemeria hybrid is illustrated in the accompanying illustration, which shows typical flower characteristics of a one-year-old plant grown in a greenhouse in the Netherlands, with colors being as nearly true as is possible for illustrations of this type. The photographic illustration submitted with this Application is a detail of flower stems of the new variety.

DETAILED DESCRIPTION OF THE NEW VARIETY

The following is a detailed description of the new cultivar of Alstroemeria hybrid as observed in a greenhouse in Rijsenhout, The Netherlands.
